Old soldier often looking for a quarrel (6)
I believe the answer is:
archer
'old soldier' is the definition.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for archer that I've seen before include "old jockey" , "Jeffrey --, Eng. author" , "stars" , "Arrows one sends" , "A 19 lord - old soldier" .)
